Conclusions
-
1.
HTTMT intensifies two-phase decomposition of martensite in the process of quenching (increases the amount of low-carbon martensite) and favors partial transformation by the intermediate mechanism in the steels investigated.
-
2.
HTTMT affects the tempering of martensite. It inhibits single-phase decomposition and increases the stability of the two-phase condition of the solid solution. During tempering after HTTMT the tetragonal solid solution is retained to higher temperatures. This may be one of the reasons that the effect of HTTMT is retained at high tempering temperatures.
-
3.
The good combination of the mechanical properties after HTTMT is due to the fragmented stable structure of martensite, the interaction of carbon with defects, and the optimal redistribution of carbon in the martensite crystals.
-
4.
The changes in the structure during HTTMT are resistant and retained at high tempering temperatures and during repeated heat treatment.
